Seismic Behavior of Reinforced Concrete Beam to Concrete Filled Steel Tubular Column Connections with Ring-Beam
In order to study the seismic behavior of reinforced concrete(RC)beam to concrete filled steel tubular(CFST)column connections with ring-beam,three specimens were experimentally studied under low cyclic loading.The influence on the sectional dimension of the ring-beam was discussed in detail.During tests,the displacement,stress,failure mode and energy dissipation capacity of the specimens were obtained and analyzed.In addition,the stress distribution of joints with and without ring-beam were respectively investigated using the general finite element analysis(FEA)software ABAQUS.Experimental and numerical results indicate that the damage of the joint with ring-beam started from the yield of longitudinal bar inside the RC frame beam; the CFST column was always in its elastic stage and no destructive damage could be seen in the RC ring-beam.Moreover,plastic-hinge came into being formed in the frame beam and hysteretic curves were often in a spindle shape.
